D3 Valve with easy-Drive Actuator

It is not necessary to calibrate y our easyDrive electric actuator prior to use from a factory shipment.
If any of the following are true, recalibration will be required (see next section)
D A change in the FloPro setting
D The actuator has been remounted o n a different valve since shipment
D Disassembly of the valve for trim or packing changes
D A new version of firmware has been loaded on the controller
The following scenarios do not require recalibrations
D New unit from the box
D Power dips or interruptions
D Changi ng of control method (i.e. from 420mA to Modbus control)
D Extended periods of storage
Calibration with the use of Modbus
1. After the unit has been properly wired and fused per instructions in the Wiring section of this instruction manual,
turn power to the unit on.
2. Calibrate using Modbus:
a. Send position command of 0% to actuator to prevent unexpected motion. Valve will move to commanded
position following the calibration procedure.
b. Send a value of 1 to register 40003. Valve plug will move t o fully open position and then to fully closed. The valve
plug will then return to the commanded position.
If a Modbus connection is not available, and recalibration is desired, use the appropriate calibration method as
determined by the control method of your valve.
Calibration without the use of Modbus
1. Turn power to the actuator off.
2. Wait for 10 seconds to ensure all circuits have discharged.
3. Return power to the actuator and use the appropriate calibration method for your control signal. Calibration
sequence must be done within 15 secondsofpowerbeingswitchedon.
4. For On/Off operation using L2e dualinput dry contact:
a. Closethecontacttocreateashortbetweenpins1and2—valveplugwillnotmoveatthistime.
b. Closethecontacttocreateashortbetweenpins1and3—valveplugwillmovetotheupper,openpositionand
then to the lower, closed position.
5. For On/Off operation using single dry contact:
a. Closethecontacttocreateashortbetweenpins1and2—valveplugwillnotmoveatthistime.
b. Open the contact to create an open circuit between pins 1 and 2 — valve plug will move to the upper, open
position and then to the lower, closed position.
